Water purifier

Abstract

A water purifier includes a water purification module that filters raw water to generate purified water, and a water outlet module that receives the purified water and outputs the purified water to the outside. The water outlet module includes a housing, a purified water inlet flow path of which at least a portion is disposed inside the housing and into which the purified water is introduced, a movable part displaced between a first position in which the movable part is retracted into the housing and a second position in which the movable part is extracted to a front side of the housing, a driving part that displaces the movable part, and a water outlet part that includes a plurality of link water outlet flow paths rotatably connected to each other and is connected to the movable part to receive the purified water and discharge the purified water to an outside.

What is claimed is:

         2 . The water purifier of  claim 1 , wherein the driving part is disposed above the water outlet part. 
     
     
         3 . The water purifier of  claim 1 , wherein the movable part moves only in a horizontal direction when being displaced, and
 when the movable part is displaced, the plurality of link water outlet flow paths of the water outlet part are unfolded or folded with both a horizontal movement component and a vertical movement component.   
     
     
         4 . The water purifier of  claim 1 , wherein the driving
 part includes: a motor fixed to the housing;   a pinion coupled to an output shaft of the motor; and   a rack bar coupled to the movable part, engaged with the pinion, and linearly moving forward or rearward according to rotation of the pinion.   
     
     
         5 . The water purifier of  claim 1 , further comprising an ultraviolet ray irradiation unit that is installed inside the housing such that the water outlet end of the water outlet part is positioned on an upper side when the movable part is located in the first position and irradiates the water outlet end of the water outlet part with ultraviolet rays. 
     
     
         6 . The water purifier of  claim 1 , further comprising an interface unit that is coupled to a front surface of the movable part, provides an operation interface, and is displaced integrally with the movable part. 
     
     
         7 . The water purifier of  claim 1 , wherein the water outlet part includes:
 a first link water outlet flow path connected to the purified water inlet flow path;   a second link water outlet flow path having a first shaft pipe rotatably connected to the first link water outlet flow path, a second shaft pipe spaced apart from the first shaft pipe and arranged side by side, and a connection pipe connecting the first shaft pipe and the second shaft pipe;   a third link water outlet flow path rotatably coupled to the second shaft pipe; and   a fourth link water outlet flow path having a third shaft pipe rotatably connected to the third link water outlet flow path and a water outlet pipe extending outward from an outer surface of the third shaft pipe.   
     
     
         8 . The water purifier of  claim 7 , wherein, when the movable part is located in the first position, the first shaft pipe is disposed in front of the second shaft pipe, and thus the third link water outlet flow path is disposed in a stacked from with the first link water outlet flow path, and when the movable part is displaced from the first position to the second position, the second shaft pipe rotates about the first shaft pipe in front of the first shaft pipe. 
     
     
         9 . The water purifier of  claim 8 , wherein the first link water outlet flow path is connected to one side of the first shaft pipe in an axial direction, the third link water outlet flow path is connected to sides of the second shaft pipe and the third shaft pipe in the axial direction, and the other sides of the first to third shaft pipes in the axial direction are closed. 
     
     
         10 . The water purifier of  claim 9 , wherein the water outlet part further includes:
 a first link stabilization member connected to the other side of the first shaft pipe in the axial direction to support the first shaft pipe; and   a second link stabilization member connected to the other sides of the second shaft pipe and the third shaft pipe in the axial direction to support the second shaft pipe and the second shaft pipe.
